i have in failure route: t_on_branch("0"); $du = "sip:127.0.0.1:5070"; xlog("L_INFO", "Pseudo variable du has value <$du>\n"); t_relay("0x01"); and i get to syslog: Nov 6 16:33:15 test /usr/sbin/kamailio[22539]: Pseudo variable du has value <sip:127.0.0.1:5070> but wireshark shows that the invite is sent according to uri host of the branch added in failure route and not to 127.0.0.1:5070. is this a bug or is it so that $du is not supposed to have any effect in failure route?
